Internal vibration modes of(n-C3H7NH3)2SbBr5 and (n-C3H7NH3)3Sb2Cl9 were studied through their phase transitions using the infrared spectroscopy. The studies show that the vibrational states of the n-propylammonium cations change considerably during the phase transitions. The v(CC), v(CN) and v-s(NH) bands are very sensitive to the phase transition at 154 K in (n-C3H7NH3)2SbBr5, and at 232 K in (n-C3H7NH3)3Sb2Cl9. IR spectra point out the key role of the n-propylammonium cations in the phase transition mechanism of both crystals.
